CM,

Have you tried INDY CYLINDER HEADS? I purchased a set of cast iron heads from them back in the late '90's for the 383 stroker I built for my '58 Biscayne. They were very accommodating and worked with me on the type of engine I was building to get the best performance and efficiency. I was very pleased. That 383 was a BEAST!! There prices were the BEST I I could find at the time. I believe they have a website. If not, check any high performance Chevrolet magazine and they usually have an ad listed.
